Piezoelectric Nitinol

Maybe you should use nitinol wire for a heat engine...

Hi Low.

actually Nitinol can work with both direct heat exchange and or electrical exchange, both can cause memory reshaping.

I was thinking about using the high voltage from piezoelectric whiskers deformation to induce an electrical charge into the nitinol to cause a reaction in the nitinol, thinner wires of nitinol react more to lessor current than thicker nitinol wires, if the gauge ratio's between piezoelectric whisker and nitinol can be equated then then it is possible to get high voltages when the metal reforms itself.

I think it might turn out more like a transformer than anything else.

This thread needs to be pursued further,I think.Wonder how this would work in a vacuum?.Quite well ,I would speculate.You can bet,a lot of this has went up as ISS experiments.Fascinating..

Also, to take this a little further it may be possible to mix Piezoelectric crystals with ferrite powder and make Piezoelectric Ferrite cores for coil windings.

the Electromagnetic induction will cause nano-malformations in the Piezoelectric-Ferrite core and cause High voltage sparks to occur.

if the mix could be made somewhat conductive then the electrical sparks might have better efficiencies.
